On the contrary, this theory was often cited as an explanation for the elevation of her second husband Otto of Northeim to duke of Bavaria.
Ursula Lewald pointed out in 1979 that it would be unusual for Otto II's sister to be his heir if he had daughters.
Until recently, it was believed that she died in March; this was based on an entry in the register of the St. Blaise church in Brunswick.
However, Sabine Borchert has shown that the Rikce ducissa mentioned in that entry was a 14th-century Duchess.
Borchert has suggested that she may have been buried in the St. Nicholas chapel of the later Harsefeld Abbey — the grave lay of the Counts of State — as she possessed land in the area and her daughter Oda was married to the Count of Stade, who resided there.
